GW Instek AFG-3000 Series arbitrary function generators include 20MHz/30MHz single isolated channel and 20MHz/30MHz dual
isolated channel models, designed to meet industry, scientific research, and education applications. Not only output channel is earth
ground isolation, dual channel models are also independently earth ground isolation, which is suitable for floating circuits (up to ±42V).
Without taking grounding reference into consideration, each channel of dual channel models can be operated independently and multi
ARB units can output simultaneously. Applications are, for instance, the ignition control or transmission device of automotive electronics.
The series features sample rate of 250MSa/s, 16-bit resolution, and 8M point memory depth arbitrary waveform characteristics. Users
can rebuild maximum 8M memory depth waveforms through using a GW Instek digital storage oscilloscope with the built-in DSOLink
function of the AFG-3000 Series.
The series supports synchronized phase for multi channel operation and the maximum phase synchronization operation is up to 6 units
and 12 channels. 10 MHz atomic clock frequency standard can be input via external signal source to elevate precision for frequency
output. The series supports frequency sweep and amplitude sweep that can also integrate functions, including linear/logarithm, one-way
(saw tooth)/two-way (triangle) waveforms, continuous/single trigger/gated trigger to meet various application requirements by applying
different sweep methods. Frequency sweep tests the frequency response of electronic components such as filter and low frequency
amplifier. Amplitude sweep simulates vibration tests (requires a vibration tester), and it also conducts aging tests of various materials
and linearity tests of low frequency amplifier.
The main features of the AFG-3000 Series include output amplitude from 1mVpp to 10Vpp (connected with a 50 ohm load);
frequency range from 1uHz to 20MHz or 30MHz; 1uHz frequency resolution; and built-in sine, square, pulse, triangle, ramp, DC voltage,
harmonic and noise. The waveform width, rise edge time and fall edge time of pulse waveform can be adjusted flexibly. Pulse waveform,
with duty cycle from 0.017% to 99.983%, can be applied as trigger signals. Users can conduct arbitrary editing via 65 built-in function
waveforms. The series supports AM/FM/PM/FSK/PWM modulation, frequency sweep, amplitude sweep and burst to satisfy industrial
application requirements. Dual channel models provide SUM modulation, coupling, tracking, and phase to meet the test requirements of
differential signal, phase control and amplifier distortion. Built-in 8th harmonic signal generator simulates harmonic signal of switching
power supplies and it also tests EMI power filter characteristics. The AFG-3000 Series provides free arbitrary waveform editing
software (AWES) for users to quickly edit waveforms from the built-in diagrams so as to execute measurements.
A.
CIRCUIT DESIGN FOR GROUND ISOLATION AMONG OUTPUT/INPUT TERMINAL, INSTRUMENT CHASSIS, AND DUAL CHANNELS
Channel 1, channel 2, reference 10 MHz input, synchronization and modulation input/output
connector grounding are isolated from instrument chassis. The output channels of dual channel
models are independently isolated. These connectors can sustain maximum isolation voltage up
to ±42Vpk (DC+ AC peak value) to earth ground that is ideal for floating circuit tests. Multi units
output can be achieved without factoring in grounding reference issue. Applications include
ignition controller or transmission devices of automotive electronics. The built-in DC bias voltage
of the AFG-3000 Series can be applied on various waveforms. The DC bias voltage is ±5V
under 50W load. For automotive electronic applications require higher DC bias voltage such as
ignition controller or transmission devices, the external power supplies can be used to bring up
the DC bias voltage to ±42Vpk (DC+ AC peak value).
B.
MULTI CHANNEL SYNCHRONIZED PHASE OPERATION
Method one uses reference frequency output (REF OUT) and reference
frequency input (REF IN), 50 ohm BNC cable (RG-58A/U) and T type BNC
connector to connect up to 6 units to conduct synchronized phase operation.
Method two uses reference frequency output (REF OUT) and reference
frequency input (REF IN) ), 50 ohm BNC cable (RG-58A/U) to connect
up to 4 units to conduct synchronized phase operation.
Users can implement multi channel synchronized phase operation up
to 6 units and 12 channels (AFG-3032/3022). There are two methods
to execute synchronized phase applications. Under different frequency,
master unit can synchronize each channel and modulate individual
phase. At 10 MHz reference frequency input (REF IN) connector,
users can input 10 MHz atomic clock frequency standard via
external signal source to enhance precision for frequency output.

CORRELATED FUNCTIONS OF DUAL CHANNEL OUTPUTS
Differential signal
Sine and cosine signal
Square signal phase adjustment
AFG-3032/3022 models support independent channel or correlated channel applications. Four correlated functions are
provided including SUM modulation, coupling, tracking, and phase.
* SUM modulation combines two signals and outputs the signal
via one single channel. Combining noise and sine waveform to
execute speaker's distortion test is one of the applications.
* Tracking function produces differential signal with same
frequency, same amplitude, and 180 degree phase
difference.
* Coupling function arbitrarily sets ratio and difference for
frequency and amplitude between two channels to realize a
simultaneous effect for all parameters of dual channel. The
example is amplifier using third order interpolation point(IP3)
measurement to simulate signal output of two different
frequency oscillators.
* Phase function arbitrarily sets phase parameters between
two channels such as simulating sine/ cosine/square
signal phase adjustment.

High Sampling Rates Achieve Higher Frequency Ranges
The profile ofarbitrary waveform is composed ofa series of
data. The frequency ofarbitrary waveform is derived from
sampling rate divided by the number ofpoints constructing
a complete waveform, i.e. frequency = sampling rate ,lthe
number ofpoints in a waveform. Based on the above, the
higher the sampling rate, the higher the arbitrary waveform
frequency can be available.

Arbitrary Editing ] Output
The AFG-BUUEI Series provides T U sets ofmemory for user
save and recall applications. Each set ofmemory is able to
store a set offront panel setting and a set ofi M-point
arbitrary waveform data. With TM long memory, AFG-3[l[l[l
can store more complex waveforms consisted ofmore data
Further more, any section ofwaveform within this TM
memory can be edited or output independently. This is a
unique feature allowing more fiexibility for user to do
waveform storage and extraction.
The AFG-3000 presents four ways to generate custom arbitrary waveforms from direct front panel operation,
PC software, a CSV file loading, and GDS-2000 series oscillosoope input.

Everything from waveform editing, I,ID configuring, and
panel setting storage and recall can be completed directly
through front panel operation. Front panel operation allows
users to edit arbitrary waveform, which is correspondingly
updated on the screen, a feature of"‘w'hat You See is What
You Get".
AFG-3000 supports CS‘v' file editing for arbitrary waveform
generation. The ESM file can be created in many ways,
including using EXCEL spreadsheet, PG client software, front
panel editing or math computing software. The computing
result ofmath software, Uctave for example, can be saved
into GS‘v' file. Edited GSM file can be downloaded from either
USE! fiash or PG to AFG-3[IIlI[I for arbitrary waveform output.

Direct Wavefonn Reconstruction from Ihe GDS-IIIII Series
The AFG-3I]I]I] can be directly connected to a GW Instek
GDS-ZUUU Series DSD with USB cable for waveform data
download. Under “DSD Link" mode ofAFG-3I]I]I], the DSD
will transfer the captured waveform data from its memory
to AFG-3I]I]I] for creating a correspondent waveform output.
Impedance Switch
AFG-3[I[I[I allows users to select the suitable impedance
between 5[I ohm and High-Z, ensuring a right impedance
compatibility.

A PG software for AFG-3I]I]I] waveform editing is supported.
The software contains not only waveform drawing tools but
also a wide variety ofwaveform editing filnctions, such as
waveform arithmetic operations. The most commonly used
waveforms, including Rayleigh, Gaussian, Normal Noise,
Pseudo Ternary, Bipolar AMI, Manchester, Differential
Manchester, RS-232, and NRZ etc., are available in the library
for user to tailor specific waveforms as needed.
